Customized kev taw qhia: Unidirectional (UD) lossis ntau ntau yam axial (± 45) qhov kev kawm) qhov pib ntawm kev ua lub zog ntawm nws / piv txwv, Hexcel Hitape® Ud Xev).
1.2 raws li phau ntawv
Rooj mov: Hloov cov khoom siv epoxy lossis cov nplaum nplaum rau kev sib khi ua ke ntawm substrates (piv txwv li, carbon fiber ntaub, honeycomb cores).
Qhov Zoo:
Hnyav-Dawb: Ze-xoom VOC emissions (ua raws li iso {1}}).
Kho Kom Zoo: Melt-txias lub voj voog yuav siv sijhawm 1-5 feeb (vs. teev rau epoxy).
2. Kev siv kev ua haujlwm thiab cov txheej txheem tshiab
2.1 kub nias
Kev ua: Pre nteg kub yaj xov ntawm fiber ntau kom kub yaj (piv txwv li, pa66: 260 mpa) → txias.
Kev ua kom ua kom zoo:
Tswj Qhov Kub: Tsis txhob muaj cov degradation fiber ntau (CF tiv thaiv<300°C).
Siab faib: Use isostatic pressing for uniform bonding (interlaminar shear strength >50 MPa, ASTM D2344).
2.2 Hauv Pwm Lamination
Daim ntawv thov: Automotive strighte feem (piv txwv li, rooj panels, roj teeb).
Cov kauj ruam:
Tshooj kub kub yaj xov nrog Carbon Fiber Prepreg → 2. Qhov chaw hauv pwm (piv txwv li, PA + GF) → 4. Sib xyaw rau ib daim.
Ua yeeb yam:
30–50% weight reduction (vs. metal), flexural stiffness >200 GPA (ISO 14125).
2.3 Nrig Fiber Ntau 3D Printing (CFTP)
Kev tawg:
Hauv-kab impregnation: Co-extrude kub yaj paj (piv txwv li, tpu) nrog cf txuas ntxiv (fiber ntau cov ntsiab lus: 50-60%).
Tsis: Nozzle temp. 220–280°C, layer thickness 0.1–0.3 mm, tensile strength >800 MPA (Cim Cim X7).
2.4 Honeycomb Cov Tub Ntxhais Kev Koom Tes
Kev Kawm Txog: Aerospace bulkheads, satellite nkhaus.
Kev ua:
Tsho Nomex Honeycomb nrog PPS Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Kub Larn → Thermally Bricbon Fiber Tais Pheej.
Peel strength >100 n / cm (ASTM D1781), Tshav kub ua hauj lwm 180 degree (deb 25.853).
